Now I have to admit to really liking the RMXP layer system - I'd choose it over the RM2K3 system any day.
Auto-shadows sounds interesting.
I never realised the dungeon generator was taken out of RMXP, to be honest.

ice to have it back, all the same.

I might wait for the American release before I download it - English from the word Go, and I'm busy until February, so I won't get time to play with it if I do download it now.
EDIT: Your site is looking good, btw.
